In a Mysuru survey of 90 people, 6 like neither pancake nor rice and 14 like both. Those who like only pancake are 10 more than those who like only rice. How many people like pancake?

Question

Accepted Answer

54. Let rice only = x, so pancake only = x + 10. Then x + 10 + 14 + x + 6 = 90, so 2x = 60 and x = 30. Pancake = 40 + 14 = 54. 40 is pancake only, 44 is the Rice circle, and 84 is everyone who likes at least one.
